本文介绍了Raml验证程序在javax.xml.validation.SchemaFactory.newSchema中引发错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
当尝试验证 espn.raml 时，我出现以下错误.相同的代码对于 gmail.raml .为什么会这样呢?供您参考，我提供了结果，发现了SchemaFactory包含的jar.
When trying to validate espn.raml I got the below error. Same code is working fine for gmail.raml. Why is this happening? For your reference I have included the results I found what are the jars that SchemaFactory includes.
axiom_1.2.11.wso2v6.jar与二进制文件匹配
axiom_1.2.11.wso2v6.jar matches Binary file
org.apache.openjpa_2.2.0.wso2v1.jar与二进制文件匹配
org.apache.openjpa_2.2.0.wso2v1.jar matches Binary file
solr_5.2.1.wso2v1.jar匹配
solr_5.2.1.wso2v1.jar matches
这是我得到的例外:

推荐答案
从raml-parser中排除xml-api即可完成这项工作.
Excluding xml-apis from raml-parser did the job.
<exclusion>
<groupId>xml-apis</groupId>
<artifactId>xml-apis</artifactId>
</exclusion>
现在可以毫无问题地进行验证了.
Now its validating without a issue.
